| X1044 GRYLLS 628 DFT c.c. F.R.B., R.W.C. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} E {Mr Elliott - Chief Engineer} /HDY. {William Hardy} 2/HP.13.8.36. Wraith II. Gearbox. We send herewith N.Sch.4873 showing the oil return from the front end bearing. It will be seen that there is free communication between the drain holes in the shaft and the rear end which receives oil to feed the 2nd speed pinion. We think that this will not interfere with the supply of adequate oil to the pinion. If it should be shown that a devision between the two sections is desirable we shall suggest that a cork is driven into the bore. E {Mr Elliott - Chief Engineer} /HDY. {William Hardy} N.Sch.4873 herewith. | ||
